If you’re looking for quite the unique gaming experience then may I recommend Memoir En Code? This title, developed by Alex Camilleri, is described as an “autobiographical game album” and that’s exactly what it is.
Imagine the experience of listening to an album all the way through. Now, apply that to game design logic .Each “track” takes players into a different bit of the story and explores events which affected the developer’s life. Included with Memoir En Code is software to decrypt a portion of the game, as well as a digital booklet.
Memoir En Code is available via itch.io for $3.99 and runs on Windows, Mac, and Linux.
